2 the most awesome components made in the world. Rick McCallum, Producer, Star Wars

3 The founders Bob Stuart studied Psychoacoustics, Electronic Engineering and Management at Imperial College, London. A passion for music soon led him to specialise in audio design. Boothroyd and Stuart met in Cambridge, discovered shared interests and philosophies in audio equipment design and founded Meridian in Since then, their designs for Meridian Audio have gained much critical and industrial acclaim, winning the coveted Design Council Award for Outstanding British Products an unprecedented three times in addition to many other international accolades. Allen Boothroyd trained as a mechanical engineer, going on to study industrial design at the Royal College of Art. The latest G Series, DVD and 808 CD players, the Processor and DSP Loudspeakers represent the culmination of these many achievements. Bob s passion for music plays a major part in his desire to ensure that the quality of an original recording is maintained indefinitely. As a result, Meridian Lossless Packing (MLP) technology was developed by the Meridian research team. These efforts were rewarded when MLP was mandated by the world s leading audio experts as the lossless compression scheme for the DVD-Audio standard a significant achievement for any audio company. Today, MLP is at the heart not only of DVD-Audio and DualDisc, but also of the emerging high-definition media specifications, HD-DVD and Blu-ray Disc.

4 Lifestyle technology The Meridian MCD-Pro was the world's first audiophile-quality Compact Disc player. It not only showed the potential of CD, but the promise of digital audio as a whole. There is one concept that has informed and inspired Allen Boothroyd and Bob Stuart and Meridian as a company from the beginning, and it s a simple one: enjoyment. Thus, the central focus of Meridian s internationally acclaimed components, loudspeakers and systems is to enhance your enjoyment and quality of life, through home entertainment. Our goal is to help you enjoy the movies you watch more, and get more out of the music you listen to. Even the award-winning styling and appearance of Meridian s Lifestyle technology components is designed to enhance your surroundings. From a compact stereo system to a custom home theatre installation, the message is the same. When you re listening to music on a Meridian system, you are brought closer to the music and the performers. We reproduce all the auditory clues that help you create an image. We help recreate the space in which the performance takes place, whether it s a world-famous concert hall or the virtual space created in a rock studio. Every nuance and detail is made clear you hear and understand on a deeper level. You enjoy the music more. Add vision to sound, and the effect is even more pronounced. Our DVD players, video processors and projectors present film-like images of vibrant colour and crystal clarity. Pictures so lifelike, you are drawn into them unaware, now, that you are looking at a screen. You enjoy the movie more. Meridian brings you closer to the performance; closer to the heart of the art. A Meridian system is the ultimate lifestyle enhancement, enriching your life and soul. We deliver enhanced enjoyment in many ways. Pioneers in the art of digital technology, we built the world s first audiophile-quality Compact Disc player over twenty years ago. Fifteen years ago we invented the DSP (Digital Signal Processing) loudspeaker, completing a pristine digital link from the studio to your listening room. Our systems often out-perform the monitoring on a soundstage movies have never sounded so good. Now, as exclusive manufacturers, distributors and codevelopers of Faroudja video products, we deliver the picture to match. But technology is no more than a means to an end and in the case of Meridian, the end is the enjoyment that your lifestyle deserves.

5 Experiencing is believing Meridian excels at complete, fully integrated systems, and the Meridian Digital Theatre is the ultimate expression of this concept. Meridian is the only company currently capable of offering a super-quality, totally digital path from disc to screen and speaker, for maximum quality and realism of both sound and vision. Yet equally, Meridian components play well with others. Our CD and DVD players provide accurate, additional sources for your existing system; our power amplifiers will drive your preferred loudspeakers perfectly. With the choice of analogue and/or digital inputs and outputs on our controllers (preamplifiers) and surround processors, Meridian can easily blend in and become a part of your life. This brochure introduces Meridian audio and video systems and components, from digital loudspeakers to amplifiers, analogue controllers to digital surround processors (another first for Meridian) from a simple, superb-quality compact stereo system to a full home theatre installation. If you need more technical information than the overview provided here, your dealer can provide a data sheet for each product, or you can find it on our web site. Just as enjoyment is the goal, so reading about enjoyment is simply not enough. We encourage you to experience Meridian audio and video entertainment products and systems for yourself. Whether you re looking for a component to complete or enhance your existing setup or a complete Meridian Digital Theatre, contact your nearest dealer (a list is available at or by calling or ing us details at the back of this brochure) and arrange a demonstration. Then bring your favourite music and/or movies, sit down, take the Meridian System Remote Plus in hand, and press Play. Only then will the sweetness of the sound and the naturalness of the image truly become clear. Try it. We promise you ll enjoy the experience and that you ll want to enjoy it forever.

6 A unique performance Our stylish DSP loudspeakers a concept we invented over 15 years ago replace passive crossovers, external digital to analogue converters and power amplifiers. Everything is in the speaker cabinet. The crossover is digital offering DSP capabilities such as optimisation and bass enhancement that are simply impossible in the analogue domain resulting in the performance you would expect from a loudspeaker four times the size, with a smoother, more natural sound that no conventional design can match. An individual precision digital converter handles each frequency band, each driving its own amplifier. Amplifiers are wired direct to the drivers they power just inches away for the ultimate in control and accuracy. Cabinet construction is equally unique, employing carefully designed combinations of laminated, bonded, metal and wood to minimise vibration, and damped with poured resins to ensure that the enclosure in no way colours the sound. We treat our loudspeakers like the quality musical instruments they are: a fact reflected in their elegant, stylish appearance. Meridian loudspeakers enhance their surroundings with their looks as well as their sound.

8 The type of system you want Stereo, multichannel or home theatre 2-channel Audio A stereo system has a place in every home, and Meridian systems deliver the very best from your Compact Disc library and other sources, including fully optimised stereo reproduction of recordings made in surround-sound. Meridian offers superb CD and DVD players that can be coupled with our analogue stereo (and dual-mono) controllers and amplifiers as well as all-digital systems consisting of as little as a player and a pair of our DSP Loudspeakers. Multichannel Audio With powerful and versatile surround controllers in both our G Series and 800 Reference Series, Meridian systems are ideal for multichannel operation, some units supporting as many as 12 loudspeakers. Employ our DSP loudspeakers, or choose analogue versions of our surround controllers with our multichannel amplifiers, and your choice of loudspeakers. The Meridian Digital Theatre Music & Film The Meridian Digital Theatre is the ultimate expression of surround sound and image for film and for music. In addition to superb sound, Meridian home theatre systems deliver unequalled high-definition images, enhancing existing sources to full High Definition broadcast quality, scaling and deinterlacing up to 1080p, thanks to Faroudja s exclusive Emmy-winning technology.

10 The style that suits you From individual components to entire systems Components to complement your existing system Often, you won t be starting from scratch: you ll want to upgrade an existing disc player, add a surround controller, or perhaps experience the world of DSP loudspeakers for the first time. Meridian s award-winning components are designed to work as part of a Meridian system, but each on their own is capable of extraordinarily high quality results when linked into your existing setup. Compact and free-standing systems At Meridian, we never forget that you need to get the best possible performance in the real world. DSP loudspeakers are much more efficient than conventional designs and can be smaller, while offering superior performance. Our controllers will render exquisite sound in stereo or surround in your home, whether it s a purposebuilt home theatre or your living room. And Meridian speakers and components are elegantly styled to suit any décor. Hidden systems Meridian s 800 Reference Series is one of the most highly rated audio/video systems in the world. Comprising the 800 Optical Disc Player and 861 Surround Controller shown here, the series also includes the 808 Signature CD Player the highest quality CD player Meridian has ever made. Or perhaps you don t want to see the system at all. Our best-selling in-wall DSP, analogue and passive installation loudspeakers offer similar performance to our free-standing models. All our components can be rack-mounted and hidden away, with RS232 remote control integrated into your home automation system and remote IR sensing.

11 Finger on the pulse The fine art of control A sophisticated modern audio/video component offers many functions which you don t need every day. But at the same time, you require quick, simple and intuitive access to the functions you do need. As a result, we ve made Meridian systems accessible on several different levels. First, you can access the vast majority of common requirements from the front panel. In the case of the G Series, virtually every function can be configured by using the front-panel display and smart keys, labelled automatically according to context. What this all means is simplicity. Put a DVD in the player and press Play, for example. Down comes the screen. The lights dim, and your system is placed in the correct surround decode mode. Without another thought. Connecting a computer to the serial port, however, allows access to every level of functionality of the component. You or your installer will perform initial setup on the system with our Windows graphic configurator. This includes setting up speaker sizes, positions and levels you probably won t need to do that again. Similarly, you can assign different sources to different inputs and determine how they should be handled analogue or digital, music or movies, in stereo or surround.

12 The G91A DVD player/tuner/controller is a complete system in a box: for stereo or surround, simply add speakers Meridian DSP systems; G Series power amplifiers and your choice of conventional speakers; or, if you prefer, a combination of the two.

14 System choices 1 2-channel compact system last bit is rendered correctly and couple it direct to a pair of our compact DSP loudspeakers, like the DSP3100s shown on the opposite page. Meridian DSP3100 DSP loudspeaker on floor stand, with G08 upsampling CD player a complete stereo system. The vast majority of music releases are on Compact Disc, and a modern CD is capable of exceptional results on the right equipment. With a Meridian CD player, especially as part of a Meridian stereo system, you ll get more out of your CD collection than ever before. After all, we invented the audiophile CD player over twenty years ago. In addition, high-resolution disc formats like DVD-Audio virtually always have stereo tracks you can choose and even if they don t, a Meridian DVD-Audio/Video player will downmix surround sources expertly to stereo. A compact stereo system thus represents an ideal entry point into the world of Meridian quality and performance. Start with a player like the G08 with upsampling and a DVD computer-style drive to ensure that every For dramatically increased flexibility, choose the G91A DVD Player/Controller/Tuner with its vast array of possibilities in stereo and surround, including analogue and digital inputs, and couple that to a pair of DSP loudspeakers. Either delivers a pristine digital path from the recording studio to your listening room, the signal remaining in the digital domain from the original recording right through to the loudspeakers. With Meridian, you can always alternatively choose an analogue path. Couple a player like the G08 and other sources to a stereo controller like the G02. Follow it with one of our stereo amplifiers and the passive speakers of your choice or use our active analogue designs like the M3100 (the active version of the DSP3100 shown opposite) or M420 in-wall. At Meridian we are masters of both analogue and digital systems.

16 System choices 2 2-channel ultimate system The 808i adds digital and analogue stereo inputs and preamplifier functionality to the basic player. Meridian 808 Signature Reference CD Player We design our loudspeakers like musical instruments which, of course, they are. Created to deliver outstanding performance for decades, they have to be capable of reproducing the sound of a Steinway or two at their real, acoustic level without distortion, something that few loudspeakers can manage: the acoustic piano is well-known as the supreme challenge for an audio system. With your eyes closed, you ll find it difficult to tell the two apart. Meridian loudspeakers will, of course, handle an orchestra, rock band or movie soundtrack equally superbly. Our highest quality, most advanced products are also highly appropriate for stereo. Take the 808 Signature Reference CD Player, for example. It s the finest-quality CD player we have ever made. Originally designed to celebrate the 20th anniversary of the introduction of our original audiophile CD player, the 808 is a limited edition, personally hand-signed by both the founders of the company, Allen Boothroyd and Bob Stuart: the multiple- Design-Award-winning team that has been behind Meridian since the beginning. The 808 will play virtually any form of audio Compact Disc, offering prodigious jitter reduction, buffering, error-correction and multi-speed read capabilities along with upsampling. The 808 makes an ideal match for our DSP8000 DSP loudspeakers once again, the top of our range. High resolution signals are passed direct from the player to the loudspeakers and the combination is truly breathtaking there is simply no better way of listening to your music in stereo. Of course, Meridian components, designed to work together as a complete system, can be mixed and matched as you require. You can equally couple the 808 to a pair of DSP5200s, or to an analogue power amplifier such as the G57 and the conventional loudspeakers of your choice.

18 System choices 3 Multichannel compact system There s no doubt that surround sound adds an extra dimension to your listening experience. Some would say that the move from stereo to surround is as impressive as the difference between mono and stereo. Don t forget, too, that there is more to surround sound than movie effects. Music in surround allows you to experience the feeling of sitting in the best seat in the house in a world-famous concert hall, or next to the producer in the recording studio. With the latest multichannel systems from Meridian, you can even experience surround sound with height. Choose Meridian DSP loudspeakers that suit your room, such as the latest compact DSP3100 or DSP5200. Then, if you wish, add one or more of our analogue/digital subwoofers, like the SW1600, to supplement the lower frequencies. You can mix and match perhaps larger speakers at the front and smaller ones at the rear to build exactly the system you require, in the space you have available. Drive the speakers with one of our awardwinning digital surround processors. Then simply tell the graphical configuration programme what your system includes, and it ll set all the components up for optimum performance whatever the size of the room or the position of the speakers. Our compact systems are ideal anywhere you want something smaller for a limited space or just less obtrusive as well as Meridian s trademark: an incredible sound. Our systems are at home in any environment. A compact Meridian surround system like that described here might be ideal for such varied locations as a luxury apartment, a superyacht, or even a personal jet. Photo: The Image Bank/Gary John Norman In addition, Meridian components include innovations such as the universally praised Trifield system, which extracts the latent surround information in high quality stereo recordings and reproduces it, stabilising the image and bringing new life to your existing stereo collection. Meridian systems have been installed in luxury yachts, personal jets, theatres, dens, bedrooms and living rooms around the world.

20 System choices 4 Multichannel freestanding systems A G Series system with DSP7000 loudspeakers at the front left and right, DSP5000HC centrechannel speaker. A Meridian surround system does more than simply reproduce the original performance: it takes you there. All the subtle cues present at a live acoustic event are reproduced, making you really believe you re sitting in the hall. Just close your eyes Reproducing whole orchestras or solo instruments in real acoustic spaces, an even more exacting task is carried out flawlessly, with incredible detail. You can listen into the music, hearing the most subtle sounds clearly. Follow a musical line in an arrangement, catch a violin harmonic or listen to the die-away of the final chord of Sergeant Pepper. Because a Meridian system can equally reproduce the virtual spaces created in a rock studio or on a film soundstage. Meridian has no equal. A Meridian multichannel system of any size is ideal for enjoying movies as well as music. The all-digital signal path preserves the most subtle nuances of the sound, so that you hear it exactly as the sound designers intended and possibly better than they ever heard it themselves from birdsong and the wind in the trees to the roar of a thunderclap or the eruption of a volcano; an asteroid crashing into the Earth or the footfall of a Tyrannosaurus Rex. And our subwoofers, like the powerful SW5500, can help you feel the impact even more deeply. Your Meridian system will meet all these challenges flawlessly, rendering from every surround encoding scheme on your discs the very best that they can offer, for a truly impressive, enveloping and stunningly real experience. Stereo material, too, can be rendered effectively into surround, for even greater enjoyment of your existing twochannel collection. In addition, our freestanding loudspeakers look as good as they sound with smooth, elegant lines and a wide range of finishes to complement any interior design or décor, from piano lacquer black and satin silver to carefully selected wood finishes (see inside the back of this brochure). Custom colours and finishes may be available to special order.

22 System choices 5 Ultimate Digital Theatre A DSP8000 loudspeaker shown with 800 Reference Series Optical Disc Player, Faroudja DVP1080 video processor and DSP5000HC horizontal centre-channel loudspeaker. The Ultimate Digital Theatre is designed for those who simply must have the very best. Meridian s state-of-the-art components offer only the highest quality and ultimate performance, for both sound and picture. Consider, for example, the DSP8000 loudspeakers and 800 Series components shown opposite. These are flagship designs upon which many of our other models have been based. They offer incredible power and accuracy a combination that only the Meridian Digital Theatre can provide. A Meridian Digital Theatre system is optimised for music, with the ability to handle, flawlessly, the entire gamut of sound: soft or loud, subtle or brash. As a result, Meridian systems out-perform the equipment you ll hear in virtually any cinema, or even an exclusive preview theatre. In fact, a top-quality Meridian system can even out-perform the audio equipment at a film studio: directors experiencing their own movies on a Meridian system for the first time have been known to remark that they have never heard their movies sound so good. Rick McCallum, the producer of the Star Wars epics, told us that Meridian offers the most awesome components made in the world. When it comes to movies, Meridian offers you an experience that can actually be superior to the real thing. Pair these exceptional audio components with the latest Faroudja digital video processors and High Definition digital video projectors, for the ultimate in sound and the ultimate in vision. This is the best DVD picture I ve ever seen, said noted film producer Arnon Milchan, experiencing the Meridian Digital Theatre for the first time. It looks like 35mm film, and the sound is incredible. Faroudja is the acknowledged leader in high-resolution, future-ready digital video processing, and Faroudja products are created and tested in our UK factory. Meridian is the only company that can offer this unique combination of market-leading digital video and digital audio. With awardwinning products revered and acclaimed around the world, Meridian leads the way.

24 System choices 6 Hidden audio systems Meanwhile, the components can be hidden too. All our units may be rack-mounted with special active racking kits that allow access to interfaces at front and rear for troublefree installation and configuration. Or perhaps you want to see nothing apart from the screen and not even that, if it rolls away for pure music enjoyment. If so, we can fulfil your requirements here, too. Our range of in-wall loudspeakers in both active analogue and digital DSP-based varieties are designed to deliver the same exquisite quality as our free-standing designs. Hide away all of the loudspeakers or perhaps only those at the rear, as you wish. The components themselves can be controlled by infrared (with a remote sensor if required) or by serial command from your home automation system. Meridian components integrate seamlessly with all the primary choices for comprehensive system control. With Meridian, you can see as much, or as little, of the equipment as you choose but you always get all the performance! Our installation loudspeaker range includes slimline systems that may be mounted onwall, offering a shallow, elegant profile; inwall, with only the grille on the surface; or flush-mounted, so that they can be installed behind wall-coverings or fabric and thus be rendered completely invisible. The 420 in-wall loudspeaker (both DSP420 and analogue active M420 are available) shown with a G68 Surround Controller.

30 Sources: Compact Disc players G06 24-bit CD Player Compact Disc is still by far the most popular medium for music, with vast numbers of titles released every year. Indeed, Meridian Compact Disc players are more popular every year. G08 Upsampling CD Player CD Audio offers exceptional results in a good playback environment, with a topquality player, and Meridian offers such players both in the G Series with the G06 and G08 and the 800 Reference Series, with the 808 and 808i. The players employ a high-speed ROM drive to reliably recover accurate data from the disc, and the G08, 800 and 808 employ upsampling to deliver the highest possible audio quality. Precision clocking and buffering minimise jitter, resulting in accurate stereo imaging and clear, clean highs. 808 Reference CD Player The 800 Reference Series includes the 808 Signature Reference CD Player, the highest quality CD player we have ever produced: each unit is personally signed by Meridian s co-designers and founders Bob Stuart and Allen Boothroyd. The 808 is available in two versions: as a player, or as a player/controller with multiple analogue and digital inputs the 808i.

32 Sources: DVD-Audio/Video players G98 DVD-Audio/Video Transport G91A DVD Player/Controller/Tuner Meridian has been deeply involved in DVD the most popular consumer electronics product ever since its inception. Meridian is the only British hardware manufacturer to be a member of the international DVD Forum, and developed Meridian Lossless Packing (MLP) initially for DVD-Audio. MLP has since been adopted by both of the emerging High Definition disc formats. Our DVD players also feature on-board Faroudja video processing technology, with full-bandwidth High Definition 1080p video output via HDMI to support the latest digital displays and automatic selection of aspect ratio according to programme content. Video inputs allow a single link from player to display, with all sources being deinterlaced and scaled by the player. 800 Reference Optical Disc Player No surprise, then, that our DVD players are consistent award-winners and frequently receive glowing reviews in the press all of them have been dubbed Player of the Year. All our DVD players handle audio and video CDs, MP3 discs and both DVD-Video and DVD-Audio discs, including the DVD sides of DualDiscs, for the very highest image and sound quality available today. Proprietary Meridian High Resolution (MHR) technology conveys encrypted high-resolution audio between player and processor. The encryption, by removing cyclic content from the digital signal, also reduces jitter, so stereo and surround images are tighter, more stable and more precise, and high frequencies cleaner. SmartLink enables the processor to know exactly what kind of content is being played, so it can select your choice of mode. The G91A is a complete system in a box: just add speakers. It s a player/controller/ tuner, with analogue and digital inputs, DAB/ FM or AM/FM tuner and a comprehensive on-board surround decode capability. It s able to drive a set of Meridian DSP loudspeakers or an analogue 5.1 system directly or combinations of the two. It s the ideal heart of a powerful stereo or surround system. Alternatively, the G98 DVD-Audio/Video player is an ideal companion for our surround controllers. And then there is the 800 Reference Series Optical Disc player. It is, quite simply, in a class of its own both for sound and vision, and needs to be experienced to be believed.

34 Controllers & Surround Processors G01 Preamplifier/Tuner G02 Balanced Dual-Mono Preamplifier G61 Surround Processor G68 Surround Processor/Tuner 861 Reference Surround Processor Analogue and digital audio are both foundations of the Meridian heritage. From beginnings in the late Seventies, when analogue was the whole story in consumer audio, Meridian has continued to develop its command of analogue technology, with good reason: it is equally important in a digital system. Then when digital audio came along in the form of the Compact Disc, Meridian was the first to offer an audiophile-quality CD player, which still stands the test of time today. Thus Meridian components offer both analogue and digital: two analogue controllers (or preamplifiers, if you prefer), the G01 and G02, offer unbalanced and true dual-mono balanced operation respectively, with optional phono modules. On the digital side, our surround processors are second to none, with analogue and coax plus optical digital inputs, and both balanced and unbalanced analogue and digital output capabilities. Three models are available. The recently introduced G61 represents an affordable entry level Meridian surround processor with a compact form-factor and an extensive range of capabilities. The G68 is available in a number of different versions, including balanced and/or unbalanced analogue outputs or analogue and digital outputs, and with or without video switching and tape/multiroom capability. The powerful, unparalleled 861 Reference unit, once again, stands on its own, with extraordinary clarity, precision and versatility. All three are packed with multiple surround decoding capabilities, including the latest AAC technology plus Dolby Digital, DTS, Ambisonics, and much more. We write our own decoder software, so we can be sure that the output is faithful to the original. The G68 and 861 include Meridian s groundbreaking Room Correction to manage troublesome acoustics. Unlike some room EQ systems, which essentially equalise your loudspeakers and not the room, MRC recognises that you probably have very good loudspeakers already, and instead focuses on smoothing the room s decay time over a range of lower-register frequencies, removing muddiness and the impact of room nodes.

36 Power amplifiers To drive your choice of loudspeakers G56 2 x 100W Stereo Power Amplifier Meridian components are designed to work together as complete systems, but they are also open-ended, thanks to our range of power amplifiers, which allow you to interface Meridian components seamlessly with conventional passive loudspeakers. G57 2 x 200W Stereo Power Amplifier G55 5 x 100W Power Amplifier Two stereo amplifiers are available one offering 100W per channel and the other 200W. We also offer a 5 x 100W multichannel amplifier for surround applications. They can also be doubled up and run in bridged mode for higher power outputs and multi-amped systems. Our amplifiers feature truly advanced design, with heavily overspecified audiophilegrade components, beefy power supplies and true toroidal transformers. Like our loudspeakers, they feature low overall feedback yet high damping, for minimum coloration and maximum performance. G51 2 x 100W Stereo Receiver The G51 receiver represents the powerful combination of a G Series stereo preamplifier/controller offering seven stereo analogue inputs and dual tape outs and AM/FM or DAB/FM tuner, with a 2 x 100W stereo power amplifier.

37 DSP loudspeakers Style, elegance and performance The DSP loudspeaker concept is a fundamental one, invented by Meridian over 15 years ago, delivering an impressive performance, even from a small cabinet. Sophisticated cabinet construction materials and techniques ensure the enclosure is free of resonances and coloration. Smooth, elegant curves enable them to satisfyingly complement your interior design. When you visit a Meridian dealer, Meridian DSP loudspeakers are probably the first things you ll notice. Their looks are unique; their sound is uniquely believable; they are like nothing else in the store. Meridian DSP loudspeakers are available in a range of wood finishes as well as piano lacquer black and silver, with other colours available to special order (see opposite inside back cover). They range in size from the compact, bookshelf-sized DSP3100 to our flagship DSP8000, offering matchless performance on all musical and movie soundtrack content. Apart from their size, all the speakers have similar sonic characteristics, so you can mix and match as your needs dictate, secure in the knowledge that they will all work synergistically together as part of your overall system.

40 Compact loudspeakers The DSP3100 Series Subwoofers For any system, analogue or digital DSP3100 DSP3100HC SW1600 An ideal companion sub The DSP3100 represents a new benchmark in the development of compact, highperformance digital loudspeakers, and is designed for use as a bookshelf or standmounted loudspeaker. Matching aluminium stands are available that may be sand-filled for maximum stability and to minimise any impact on sound quality. The vertical units also include universal wall bracket mountings for additional flexibility in location. The horizontal centre unit is magnetically shielded. The DSP3100 is available in black or satin silver (illustrated) matching the finish of G Series units. The speakers are tonally similar to other Meridian DSP loudspeakers and as a result they are ideal for use, for example, as surrounds for a Meridian DSP-based system. They are equally suited for use in a smaller stand-alone system in a study or bedroom, and can be used as second zone speakers in a Meridian multiroom environment. The extremely accurate characteristics of the DSP3100 make it eminently suitable for studio monitoring applications, particularly as a near-field or surround monitor in recording and mastering facilities. An active analogue version, the M3100, is also available. Our smaller DSP loudspeakers and systems in general, Meridian or otherwise, are ideally complemented with one of our analogue/digital subwoofers, the SW1600 and SW5500. They combine the finest materials with state-of-the-art design to create what we believe are the ultimate subwoofers, emphasising extreme bass, depth, clarity, control and articulation. Each subwoofer provides both digital and active balanced/unbalanced analogue inputs. They are based on 300mm (12in) highefficiency long-throw custom bass drivers. The SW1600 uses a single driver, and the SW5500 includes two. In both cases, the enclosure is sealed for maximum flexibility of positioning. They are driven by Class G high efficiency ultra-low output impedance amplifiers. The combination of idealised magnetic design, careful star earthing, and very fast output devices gives the amplifiers extremely low noise and fast bass, optimised for both music and movie soundtracks. Cabinets are constructed from 22mm wood with inert basket bracing and bitumen damping to produce an ultra-rigid cabinet that minimises coloration and resonance. Protection circuitry continually monitors driver behaviour for superior performance.

42 Smaller loudspeakers The DSP5200 Series DSP5200 The DSP5200 takes the elegant appearance and advanced design of Meridian s flagship DSP8000 and popular DSP7000 and delivers them in a compact package under 36in tall, with a horizontal centre available to match. Ideal for more spacious as well as smaller rooms, these loudspeakers will do justice to any system, in almost any environment. DSP5200HC SW1600 An ideal companion sub Each DSP5200 combines a digital crossover design, three custom drivers, three amplifiers, two multi-bit delta-sigma digital converters and computers to deliver an impressive, uncoloured and accurate sound. Powerful digital signal processing technology gives the DSP5200 uncompromised, precise detail with pinpoint imaging and dimensionality in both stereo and surround. Advanced signal processing packs dynamics and bass into a compact, beautiful-looking enclosure. DSP controls allow correction for a variety of locations. The stylish, curved and tapered cabinet construction is of 19mm thick multi-layer materials, and is inherently stiff with superior geometry and damping. This configuration, along with active operation, driver selection and DSP correction, delivers a combination of smooth, powerful bass and very low coloration.

44 DSP5000 & DSP5500 loudspeakers Slim, single-box designs with maximum versatility DSP5000 DSP5500 The DSP5000 and DSP5500 loudspeakers are front-facing single-box designs that can be built into system cabinets DSP functions are provided to correct the frequency response in different locations. Each of the drive units has its own 75W power amplifier. DSP5000HC DSP5500HC The DSP5000 is a 2½-way speaker, with three custom drivers, three amplifiers, two delta-sigma digital converters, digital crossovers and computers for maximum performance in a compact slimline cabinet. It offers uncompromised precise detail and stereo dimensionality unequalled for its price; advanced signal processing packs dynamics and bass into a compact, slimline package. SW1600 subwoofer An ideal companion subwoofer for either of these systems SW5500 subwoofer An ideal companion subwoofer for either of these systems The 3-way DSP5500 includes removable wood and steel bolted side panels, which allow easy colour changes or custom finishes. The bass system uses two 200mm long-throw composite bass drivers. The cabinet vents through a floor-level wide-area coupling slot; this configuration, along with the active and DSP correction, maintains smooth powerful bass in the room down to 30Hz with very low mid-range coloration. The mid-range is a custom 160mm polypropylene driver in a separate enclosure.

45 DSP7000 loudspeaker The essence of the DSP8000 distilled into a smaller cabinet Like Meridian s flagship design, the DSP8000 (opposite), from which it is derived, the elegantly styled DSP7000 is breathtaking in its ability to place musicians in precise locations in your room, with even subtle body movements clearly audible. The system has the power to bring to life the most challenging orchestral or solo performance, soundtrack or rock band, with the innovative cabinet and drive technology necessary to deliver the demanding dynamic resolution required by today s advanced audio formats. Each unit employs two high-efficiency longthrow custom bass drive units. The treble and mid-range drivers are mounted in a separate acoustic enclosure: the former is a semi-horn-loaded composite dome design with a silver voice coil, while the mid-range uses a custom 160mm polypropylene driver. The drivers are powered by four independent high-power, low-feedback amplifiers with extremely low noise, high detail, and fast bass. The electronic assembly is powered by a substantial toroidal transformer feeding high-quality audiophile-grade capacitors. The precision cabinet uses innovative design techniques to give exceptionally low coloration and exquisite mid-range transparency.

46 DSP8000 loudspeaker Our flagship digital design Meridian s flagship loudspeaker, the DSP8000, sets entirely new standards for clarity, dynamics, imaging and realism. The DSP8000 is designed to reproduce sounds at up to full natural level while providing all the resolution required by sources of up to 24-bit and 192kHz sampling. A new approach to cabinet construction, employing unique interlaminated metal/wood materials, was developed especially for this product, along with the careful selection of advanced drive unit materials. Each DSP8000 loudspeaker uses six multiple high-efficiency long-throw custom bass drive units. The bass units are mounted symmetrically in pairs on the sides of the bass cabinet, cancelling vibration in order to minimise interference with the mid-range and treble units, which are mounted in a separate, sealed head assembly. The treble unit is a semi-horn-loaded composite dome design with a silver voice coil. The midrange unit incorporates a cone made from a uniquely light and stiff combination of polymers to give unparalleled transparency. The speakers are driven by five independent high-power, low-feedback power amplifiers, mounted on a specially extruded multi-finned heatsink.

48 Installation loudspeakers Offering hidden benefits DSP420/M420 in-wall 200 Series in-ceiling G41 Speaker Control Unit G46 DSP Speaker Control Unit P330W in-wall system elements Meridian s installation loudspeakers have rapidly become some of the company s most popular loudspeaker products, with their ability to deliver Meridian s signature DSP technology and performance in a virtually invisible, installed design. To the original DSP420, which shares performance characteristics with our stand-alone designs, we have added the M420, an active analogue version with the same drivers and power amplifiers. The back-box includes the analogue or digital input board and power termination in their own sealed enclosures, and the units can be mounted flush (completely hidden) or in-wall (with surface grille). Our new 200 Series in-ceiling designs and the 300 Series of in-wall and on-wall systems allow exceptional flexibility of configuration. They can be supplied as passive speakers to be driven by external conventional amplification; as an active analogue system driven by a G41 Speaker Control Unit, including 8 x 100W power amplifier and modular plug-in electronic crossover, which can handle up to five channels of audio; or as a DSP system, driven by a G46 DSP Speaker Control Unit with DSP crossover and 8 x 100W power amplifiers. The G41 and G46 Speaker Control Units have the same form factor and appearance as the other G Series units, and can be mounted with the G Series Active Rack kit. The 200 Series of in-ceiling speakers are 2- way designs with an 8in (200mm) bass driver, pivoting tweeter and optional crossover, for either surface grille or flush mounting. The 300 Series consists of three ultraslimline systems for in-wall (surface grille), flush-mount (completely hidden, eg behind wall coverings) and on-wall applications, featuring 6.5in (165mm) bass drivers, and a wide-dispersion ribbon tweeter for superb performance anywhere. Units are supplied with or without passive crossover. A white paintable grille and frame is included, and rough-in boxes are available. The 320 includes a single bass driver and tweeter; the 330 (opposite) adds an 8in (200mm) Auxiliary Bass Radiator (ABR); and the 350 features two bass drivers and two ABRs. In every case, Meridian installation loudspeakers deliver the performance of a stand-alone design in a discreet enclosure with minimal visual impact and awesome power.
